摘要： Lightning strike protection films, along with related assemblies and methods, are provided. These films include an electrically-conductive layer having a plurality of perforations arranged in a hexagonal lattice pattern, wherein the perforations are generally hexagonal. Advantageously, conductive films based on hexagonal perforations can provide greater protection than circular holes for the equivalent weight conductor, thus providing superior lightning strike protection for a given weight.

摘要： Provided are articles, along with related methods, capable of providing an effective adhesive bond to a substrate containing polyetherketoneketone. The multilayered article includes a substrate comprising polyetherketoneketone, an adhesion promoter disposed on the substrate, the adhesion promoter comprising at least one of organotitanate, polyamide, surface-treated nanosilica, ammosilane or epoxy silane, and an adhesive bonded to the adhesion promoter. The adhesive contains at least one of an acrylic polymer, a polysulfide, a polythioether, an epoxy resin, or a silicone resin.

摘要： A method of making an electrically-conductive film is provided. The method includes providing a release layer, optionally having a topologically structured surface, and depositing at least one electrically-conductive layer on the release layer whereby the at least one electrically-conductive layer has an outer surface that substantially replicates the topologically structured surface. The electrically-conductive layer can be peeled away from the release layer to obtain the electrically-conductive film. Such electrically-conductive films can be useful in lightning strike applications.

摘要： A lightning protective seal cap comprising a seal cap that defines an interior, and a quantity of an uncured sealant that is curable by the application of actinic radiation so as to bind the seal cap to a fastener. The interior of the seal cap contains the quantity of uncured sealant, the seal cap is positionable over the fastener such that at least a portion of the fastener resides in the interior of the seal cap, and when the seal cap is in position over the fastener, the sealant containing seal cap prevents electrical arcing to the fastener from a lightning strike.

摘要： Methods of using and repairing seal caps as well as constructions comprising seal caps, including in some embodiments seal caps which may be useful in sealing fasteners that protrude into fuel storage cells in aircraft. In some embodiments, methods include the use of optically translucent seal cap and application of a second quantity of sealant to fill voids observed within the interior of the seal cap after cure of a first quantity of sealant.

摘要： Presently described are methods of making coating comprising aqueous fluoropolymer latex dispersions, aqueous fluoropolymer coating compositions, coated substrates, and (e.g. backside) films of photovoltaic cells. In one embodiment, the film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; inorganic oxide nanoparticles; and a compound that reacts with the repeat units derived from VF and VDF to crosslink the fluoropolymer and/or couple the fluoropolymer to the inorganic oxide nanoparticles. In another embodiment, the backside film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; and an amino-substituted organosilane ester or ester equivalent crosslinking compound.
